OptionalfanOptional device-specific fan-speed fn values, ordered by canonical fan speed ([auto, low, medium, high, max]).
E.g. [1, 2, 4, 6] for CodeNum=1117 devices means auto=1, low=2, medium=4, high=6. When absent, a legacy universal
mapping is assumed.
Array of supported remote control key codes
Available operating modes with their supported temperature settings
Temperature range as [minimum, maximum] in device units
Version string of the capability definition
Supported capabilities and features for air conditioning devices.
Defines the operational parameters and available functions for AC units, including temperature ranges, operating modes, and supported control keys.
